WAY TO PROTECT RADARS AGAINST ANTIRADAR ROCKETS AND RECONNAISSANCE AIRCRAFT Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: invention is related to technology of protection of radars against antiradar rockets and from detection of their positions from reconnaissance aircraft equipped with airborne direction finding facilities. Invention consists in matched fast-alternating quasi- coherent radiation of signals by additional radiation sources-brightening stations controlled by protected radar and forming in aggregate alternating non-linear structure of wave front near antiradar rockets and reconnaissance aircraft. Achievable technical result consists in reduced probability of either radar destruction or determination of its coordinates thanks to inability of homing head of antiradar rocket and direction finding facility of reconnaissance aircraft to determine actual position of radiation source for short time period. EFFECT: reduced probability of radar destruction and determination of coordinates of its position. 2 dwg
